SLUG-EXPELLER MECHANISM FOR LINE-CASTING MACHINES.

Specification of Letters Patent.

Patented Dec. 9, 1913.

Application filed January 15, 1913. Serial No. 742,088.

To all whom it may concern Be it known that I, ARTHUR \V. Ln Bonnr, a citizen of the United States, residing at Noonsocket, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improve ment in Slug-Expeller Mechanism for Line- Ca-sting Machines, of which the following is a full, clear, and exact description.

This invention is for use as part of a machine in which line-long printing slugs or type bars are cast from assembled lines of matrices, are trimmed to uniform size, and are delivered into a galley. In such machines are many movable parts which are concerned in the casting and delivery of the type slugs; and in order that the desired results shall be attained without breakage or other disaster, it is necessary that said parts move in proper synchronism through their entire cycles of operation. Each of such machines has a movable mold, which moves between the casting and ejecting positions, and vice versa. Also there are side trimming knives before which the mold should come to rest when it is in the slug ejecting position. Also there is an expeller blade which, by its movement, forces the type slug out of the mold and between the trimming knives and to the mechanism by which the slug is delivered to the galley.

The present invention relates to the mechanism for moving said expeller blade; and the object is to provide suitable mechanism for this purpose which will operate when and only when the movable mold has taken its proper position behind the trimming knives and in front of said expcller blade.

The invention includes a guided ejector slide to which the ejector blade is secured, a power driven movable member, a hook arm movably mounted on the slide and adapted for engagement with said movable member, and means normally holding said hook out of the engaging position, and means whereby the mold in the last part of its movement to the ejecting position will cause the release of this hook, so that it may, when the mold has reached the ejecting position, move into such operative engagement with the movable member, that the latter may move the ejector slide on its slug ejecting journey.

The precise novel combinations of parts which constitute the present invention are shown in the accompanying drawing, and hereinafter described and pointed out definitely in the appended claims.

In the drawing, Figure 1 is a plan view of slug ejecting mechanism and associated parts embodying this invention, when the mold is in the ejecting position. Fig. 2 is a plan view of certain parts, which are shown in Fig. 1, when the said parts are in the position they occupy just before the mold reaches the ejecting position. Fig. 3 is an elevation of the mechanism shown in Fig. .1 as viewed from that side thereof which is at the top of Fig. 1. Fig. 4L is a detached rear view of the plunger It and associated parts. Fig. 5 is an elevation of the same mechanism which is shown in Fig. 1, as viewed from the left side of Fig. 1.

The invention in the precise form shown is contrived with special reference for use in a machine, wherein the mold H moves in a straight horizontal path backward and forward between the ejecting and the casting positions. The invention is also particularly contrived with reference to its use in a machine wherein the power to move, through their several cycles, all of the Parts concerned in the casting and slug ejecting mechanism is taken from a single shaft A, which, at the will of the operator is caused to turn through one complete revolution, and to then stop. In that machine, when the shaft stops, the movable mold comes to rest, or should come to rest in the slug ejecting position. The mold which is shown sufficiently for the present purpose may be substantially such as is shown and described in Letters Patent No. 1,027,551. That is to say, the mold proper of part M in. which the mold slot is formed, is carried by a saddle M to which the power to move the mold is applied, while the mold proper is movably supported upon that saddle and is normally held in the desired relation thereto. In case the mold proper meets with any obstruction to its movement into the ejecting position, the saddle may move without breaking anything. Commonly, of course, there is no interference with the complete movement of the slot-carrying part of the mold into the ejecting position; but something may get in the way of the mold, for example, the chips which result from the trimming of the slug to size may fly into some position such as to interfere with the complete movement of the mold to the ejectingposition. Obviously, the slug ejecting slide will cause something to'break if it starts on its slug ejecting movement when the mold is in a position such that, instead of engaging only the slug in the mold slot, the ejector blade-engages some part of the mold.

The mechanism through which the power shaft A imparts its required backward and forward movement to the moldis not. a part of this invention, and. therefore is not shown; but such mechanism may be substantially like thatwhich is shown and described in my. prior application, Serial Number 736,489, filed December 13, 1912. On: this shaft. A. isa cam a, which, by its action, on an arm- Z). causes the rocking of rock shaft 13..

G represents the guided: expeller slide which is .movable horizontally in apath at right angles to the path of the mold; that is to say, the mold moves forward and back ward, and the ejector slide moves fromright.

to left, and vice versa. The eXpeller blade 9 isfixed to thisslide. The mold path is between the expeller blade and trimming.

knives K., The expeller slide, and the trimming knives are placed in such position that when the mold comes to rest in the expelling position the eXpeller blade in'its forward movementw-illenter the mold slot and push the slug therefrom and between the trim ming knives.

H represents a pivoted leverv in bell crank form. Thesubstantially horizontal arm of this'lever is-connected by links J, J and I with an arm 5 fixed to the rock shaft B, before mentioned.

A book N is pivoted cna horizontalpivot to the, eXpe-ller slide and extends rearwardly theii'efrom. It has a hooked shape notch a inthe under side of. its rear end, which is adapted to fall over and embrace a pin it carried by the upper end of the bell crank.

H. One wall of. thisnotch extendsdownward considerably farther than the other, so that, when the hook. is in its normally raised position, as shown in Fig. 5, and the bell crank lever is rocked in one direction the pin it will engage the hook andthereby move it and the slide G in the slide retracting direction; butif the bell crank lever H is rocked in.,the contrary direction, pin 71. will move under and out of contact with the said hook. This hook N has an upwardly projecting tail: piece 72. which normally,

that isto say, when the expeller slide is at rest in'its retracted position, rests against the expeller preventer P, and thereby the 100k is held in its elevated position. This expeller prevent-er is ablock fixed to a plunger R which is movable in ahorizontal di-. rection at right angles to the direction of the eXpelle-r slide. This plunger is subject to carries on its outer end and pivoted to it on a vertical pivot a trigger T which, by virtue of azsmall plunger, t and a spring t tends to assume the position shown in Fig. 2. vVhen in this position the short arm of this trigger lies just inside of and in engagement with the side of a lever U,the other end of which lever lies in the path in which the slot-carrying part M of the mold moves in going to the slug ejecting position. l/Vhen the mold moves into the proper slug ejecting position, this slot-carrying part M of the mold engages the lever U, or rather it engagesan adjustable set screwa in the end of said lever, and thereby rocks the lever. The other end of the lever, by its engagement with the short arm of the trigger, will move said trigger and the plunger R, to which it is pivoted, in opposition to the plunger spring until the gap 7 in saidplunger is brought into alinement with the tail has been accomplished, the rock shaft B will be rocked in the direction such that, through the described" intermediate mechanism, the horizontal arm. of the bell crank lever will be pulled down, and the vertical arm thereof moved toward the right, as shown in Fig. 5. The pin it carried by said lever being in operative engagement with the hook N, willpush it; and the'hook will, inturn, push the expeller slide which carries it in the slug ejecting direction, with the result of pushing the slug out of the properly positioned mold slot and between the trimming knives. V

The expellerslide carries an adjustable setscrew Y placed so that justas'the slide has finished its slug ejecting movement, this set screw willengage with the long arm of the trigger T and will rock it on its pivot. into the-- position shown in Fig. 1. This frees the trigger and plunger R from. restraint; whereupon the plunger willbe moved by its spring back to its-normal position. In so movingit carries the'trigger with it, and

thereby the short end of the trigger is left its spring a to the position shown in Fig. 2; following which the trigger will be moved by its spring to the position also shown in the same figure. When the expeller slide has been moved to its retracted position, the tail piece a on hook lever N will engage with the eXpeller preventer P; and its hook shaped end will thereby be lifted to the position shown in Fig. 5.

The lever U, as shown, is made of two pieces U U both hung on the same pivot. This last named part is connected with the adjacent part U of the member U by means of a spring pin Z. By witlulrawing this pin, the two parts oil? the lever may be disconnected, and this will, permit the part U to be swung out of the Way of the mold so that the mold may be removed it occasion for so doing occurs, because the lever U does not project into the path of said mold.

From the foregoing it is quite evident that if the mold does not move completely into the ejecting position, it will. not sulliciently rock lever U, and therefore the mechanism operated thereby will not be moved so as to allow the hook shaped lever N to drop. In that event, although the bell crank lever H will be rocked as usual, this rocking movement will cause no i'novement of the ejector slide in the slug ejecting direction.
